LETTER FOR LlNOTYPE-BARS.

SPECIFICATION forming part of Letters Patent No. 565,252, dated August4, 1896.

Application filed February 7, 1896. Serial No. 537,628. (No model.)

To all whom it may concern:

Be it known that I, ANDREW B. ADAIR, a citizen of the United States,residing at the city of Evanston, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Letters forLinotype- Bars, of which the following is a specification.

My invention relates to improvements in type-bars, usually calledlinotypes; and the object of my invention is to produce a type-barhaving a letter which will extend over the space occupied by two or moreof such type-bars as are produced upon linotypemachines. Heretoforeletters extending over more than one line of type produced upon suchmachines have been made by casting upon one of the type-bars letterswhich extend beyond such bar, but which when placed in position forprinting must be supported by the type-bar next adjacent to it. Thedisadvantage of this construction is that it frequently happens inpractice that the lower or projecting portion of such letter is notfirmly supported by the adjacent type-bar when the type-bars areassembled, and owing to the great pressure which is necessary inprinting from type-bars, or producing a matrix from such type-bars, suchprojecting portion of the letter is liable to be broken or bent so thata proper impression cannot be obtained from it. My invention obviatesthis difficulty without any necessary change in the mechanism of themachine upon which'such typebars are produced.

My invention can be accomplished on any of the machines now used forproducing typebars; but as an illustration of a machine for producingsuch type-bars I refer particularly to the machine invented by OttmarMergen thaler, as shown and described in Letters Patent of the UnitedStates No. 378,798, dated February 28, 1888, for a machine for producingtype-bars.

The process by which my improved typebar is produced having suchtwo-line letters, or letters covering more than two lines, consists inarranging the letter in separate parts, so that one part of the lettershall be supported upon one of the type-bars and the other part or partsof the letter shall be supported upon the type bar or bars nextadjoining it.

This process may be accomplished in at least two different modes.Taking, for example, a letter intendedto cover two or more lines ofprinted matter, in one mode the whole of the letter is cast upon one ofthe type-bars, the lower part of the letter projecting below the face ofone of the type-bars, but in the plane of such face and without support.One of the usual cutting or trimming knives -adjacent to the mold-diskthen cuts ofi the projecting or unsupported portion of the letter. Thewhole letter is again cast upon the next type-bar, the upper part of theletter projecting above the face of the type-bar in the plane of saidface and without support beneath it. The part thus projecting is in likemanner out off by one of the usual knives, so that when the two parts ofthe letter remaining upon the face of the type-bars are brought togetherthey will form a single letter covering at least two lines. Of coursethe letter must be cast upon the'proper portion of each of the typebars,and in such relation thatwhen the two bars are assembled one lettercovering two lines will be the result. The other mode of preparing atwo-line letter is to cast one part of the letter upon one of thetype-bars and the remaining portion of the letter in its appropriateplace upon the next adjacent typebar. This is accomplished by the use ofmatrices having the proper parts of the letter stamped or cut therein,the two type-bars being then properly assembled to form a singletwo-line letter.

The same processes may be applied to the production of a letter coveringmore than two lines.

Referring to the drawings which accompany and form a part of thisspecification, Figure 1 is a perspective view of two type-bars havin gletters formed thereon in accordance with the process first described.Fig. 2 shows the type-bars assembled with portions of the let ter oneach bar. Fig. 3 shows type-bars having the letters formed in accordancewith the second process set forth.

A denotes the type-bars, and H the letter which is intended to cover twolines. In the type-=bar shown in Fig. 1,which is formed in accordancewith my first process, the letter H is formed as an entirety on thetype-bar,

joining type-bar has the same letter cast on its face, as shown, but theother half of the letter is cast on the second type-bar, while. thatportion of the letter II which in the firstdescribed bar is attached tothe face of the type-bar projects beyond the edge in the, It will beapparent that when present case. the projecting portions of the twoletters II are cut away and the type-bars assembled the remainingportions of the two letters will form a complete two-line letter.

In'the second process which I have set forth I form, in casting, but onehalf the letter H i on each bar, thus doing away with the necessity ofcuttingawa-ythe projecting portions of the letters, the parts assumingthe same positions when the bars are assembled as in thecase firstdescribed and-as shown in Fig. 2.

A type-bar having portions of a three-line letter formed thereon mayalsobe formed by 1 following either of the processes set forth above, andthe structure-of such three-line letter is so obvious that it is notdeemed nec- 1 essary to illustrate or describe this in detail.

two-line letters of suclrconstruction that the letter shall beproperlysupported so as to make an even impression. So far as I am awareI am the first to make a linotype-bar having a portion of a letter orcharacter formed thereon and intended to register with other portions ofthe same letter formed on adjacent bars.

What I claim as new, and desire to secure by 'Letters Patent, is-

1. A 1inotype-bar having a portion of a letter orcharacter formedthereon, said bar being intended to cooperate with the adjacent bar toproduce a letter or character covering a plurality of type-bar spaces.

2. A linotype-bar havinga portion of a letter or character formedthereon, said bar being adapted to cooperate with an adjacent bar,bearingthecomplemental portion of said letter, to fornia letter coveringa pluralityof type-barspaces.

3. As an improved article of manufacture, a linotypesbarprovided withcomplete letters orcharacters on its printing-face,-and having afragmentor ,portionof a j-letter or character in printing :alinementwith said complete characters, said letter-fragment being intended tocooperate with .complemental parts or adjacent bars to produce a lettercovering two or more type-bar spaces.
